The DSR shall be supplied with all air filters, flow indicators, communication cables, hoses, and connectors necessary for operation. The DSR upper and lower test plates shall be serialized via permanently machined etching of traceable serial numbers on each upper and lower test plate. Each test plate shall be delivered with documentation of precise plate diameters as required by AASHTO T 315 and ASTM D7175 reporting requirements for test plate diameter. One set 8mm and 25mm upper and lower test plates shall be provided. The DSR shall have automatic recognition upon connection of upper test plates and chambers which transmits the model and serial number of each component to the control system (computer software). The precise plate diameter of each upper plate must also be transmitted via the automatic recognition system. Information automatically dispatched to the software via the automatic recognition system shall include, at minimum: plate name, plate serial number, exact plate diameter, coefficient of thermal expansion of plate, and operating temperature range of the plate and/or chamber. The user shall not need to enter any details regarding the upper test plates geometry or serial number in the DSR software. Automatic recognition system should not require special placement or rotational motion of the upper measuring systems for detection. DSR software shall actively use the upper measuring system information real time preventing need for user to load a measuring system file prior to the test based upon the measuring gap to be used. The DSR must have automatic detection and test abort when measuring systems or chambers not designed for use with a particular template are installed. The DSR shall be delivered with these capabilities and capabilities demonstrated during installation. The DSR shall utilize a quick connect coupling system which provides one-handed quick-connect coupling of the upper test plate to the instrument. The quick connect coupling system shall be of design such that re-zeroing of the gap is not necessary after upper test plate removal for cleaning. Systems utilizing a screw-on mechanism or draw rod for affixing upper test plates will not be considered. The DSR shall be delivered with these capabilities and capabilities demonstrated during installation.
